Using Splunk from the command line

Almost everything that can be done via the web interface can also be accomplished via the command line. For an overview, see the output of /opt/splunk/bin/splunk help. For help on a specific command, use /opt/splunk/bin/splunk help [commandname].

The most common action performed on the command line is search. For example, have a look at the following code:

$ /opt/splunk/bin/splunk search 'foo'

2012-08-25T20:17:54 user=user2 GET /foo?q=7148356 uid=MzA4MTc5OA
2012-08-25T20:17:54 user=user2 GET /foo?q=7148356 uid=MzA4MTc5OA

• By default, searches are performed over All time. Protect yourself by including earliest=-1d or an appropriate time range in your query.
• By default, Splunk will only output 100 lines of results. If you need more...
